Implementación de prototipos de sistemas de alerta basados en comunicación inalámbrica : implementación de un prototipo de sistema de alerta por detección de sonido.

Abstract

The present degree project of a prototype of a sound detection alert system is composed of an Arduino Uno board, an ESP32 module that has a chip that allows it to establish a wireless connection, a KY037 sensor and display; these electronic components are integrated into a wooden box with acrylic front face. The purpose of the system is to scan the noise produced in less controlled environments such as libraries or auditoriums in order to maintain the minimum noise possible since these environments are the ones that need it the most; at the same time it will produce alerts when the system detects that the established noise limit is exceeded. The document has 5 sections. The first part presents the problems that exist in less controlled environments and the sound levels to which they are subjected. It also explains the operation of the prototype; in addition to showing the objectives, scope and technical characteristics. The second part explains the methodology used for the development of the prototype. The third section details the process that began with the search for the different electronic elements. It goes through the design and implementation of the board, which includes the corresponding calculations, the code flow diagram, the circuit diagrams and the case, as well as the process of elaboration of the board and its commissioning with the respective operation tests. The fourth and fifth sections include the conclusions and recommendations obtained with the implementation of the developed prototype, including suggestions for future improvements to the system.
